Patented Aug. 6, 1946 CONTROL MECHANISM FOR DISPENSING APPARATUS Harvey E. Marvel, Fort Wayne, Ind., assignor to S. F. Bowser & Company, Incorporated, Fort Wayne, Ind., a corporation of Indiana Application July 13, 1940, Serial No. 345,353

This invention relates to a mechanism for controlling and locking up the delivery means provided in the usual filling station gasoline dispenser and. comprises a novel nozzle support and operating connections between said support and the motor control switch which is usually provided in such apparatus.

It is an object of the invention to provide a nozzle support which is rugged and which at the same time is simple in construction and attractive in appearance.

It is a further object of the invention to provide a nozzle supporting and switch controlling mechanism which will not support the nozzle in the switch-on position of the support but which positively supports the nozzle in the switch-off position.

Yet another object of the invention is to provide simple means for locking the nozzle on the support and for preventing ready access to the nozzle valve trigger in the locked up position.

Another object of the invention is to provide a switch operating nozzl'e support which lends itself to one handed operation.

Still another object of the invention is to provide a switch operating nozzle support which compels the restoration of the nozzle support to the switch-off position before the nozzle can be placed on the support. Thus two complete acts must be performed in predetermined sequence to produce the result of returning the nozzle to supported condition.

A further object of the invention is to provide a nozzle support which retains the nozzle securely supported in the service or unlocked condition so that it cannot be dislodged by ordinary hose movements.

It is also an object of the invention to store the locking member in position in which it will not interfere with the manipulation of the nozzle-or the support when the device is in the unlocked condition.

These and other objects will become apparent from a study of the specification and the drawings which are attached thereto and form a part thereof and in which:

Figure 1 is side elevation of a dispensing apparatus with parts of the housing broken away to show the nozzle support and its related reset interlock and switch operating mechanisms.

Figure 2 is a front elevation showing the mechanisms of Figure 1 and a nozzle in place on said support.

Figure 3 is a front elevation of the nozzle support with the locking member shown. by full lines 19 Claims. (Cl. 222-74) in looking position and by dotted lines in the unlocking position.

' Figure 4 is a side elevation of the nozzle support of Figure 3 with the locking member broken away to show the relation of the parts of said support and those of a nozzle.

Figure 5 is a section taken on the line 5-5 of Figure 3.

Figure 6 is a sectional view taken on the line 6-6 of Figure 4.

Referring to Figure 1, numerals I indicate the frame of the dispensing apparatus, 2 indicate portions of the housing of the apparatus and 3 is used to indicate a shroud for the nozzle tip 4.

A hose connection 5 is shown in Figure 1 and this is adapted toreceive one end of a hose 6 to which is attached the usual nozzle 1. The nozzle is provided with a valve indicated generall at 8 having a projecting stem 9 which is actuated by a trigger or operating lever ill, the lower portion of which stands away from a guard l 2, is adapted to be manually engaged and serves as the operating portion of the lever. The latter is pivoted at l I to a portion of the nozzle guard l2.

The nozzle support comprises a back plate l3 which is preferably a casting which is mounted by means of screw fastenings not shown through the cross member l4, Figure 1, which forms a part of the dispensing apparatus frame. Formed integrally with the back plate is a horizontal boss 15, best shown in Figure 5, which is adapted to receive a sliding shaft I6. The outer end of the shaft is provided with a projection l1 which-is adapted to enter a hole [8 in the nozzle supporting member [9. The projection is riveted over after passing through the hole I8 as to hold the member l9 rigidly on the shaft [6.

Also, projecting from the back plate I3 is a boss 20 which is provided with a lateral, horizontal projection 2|, thus forming a hook which lies substantially parallel with the main portion of the back plate I3. This hook is disposed above the boss l5 and is adapted to engage the trigger guard [2 as is clearly shown in Figures 2 and 4.

Projecting backwardly then laterally from the right-hand side of the nozzle supporting member l9, as shown in Figures 1 and 3, is a lock receiving projection 22, the free end of which lies in a substantially vertical plane disposed perpendicular to the axis of boss l5 and shaft l6 and which is perforated as shown at 23 to receive a hasp of a padlock not shown.

The nozzle support [9 also comprises a member 24 which is bent backwardly above shaft I6 and thence upwardly, as shown at 25, to form an angle in which the lower corner or bend of the nozzle guard |2 may be received as shown in Figures 2 and. 4. The member 24 is inclined upwardly toward the member 25 so that should the nozzle be rested on the element 24 when it occupies the position shown in Figure 5, it would tend to slide to the left as shown in Figure 5 and fall off at element 24. It will be seen, however, that when the shaft |8 occupies the position shown in Figures 2 and 4, the vertical section of the nozzle guard will be received between the back plate I3 and the hook 2| so that such sliding of the nozzle from the support as was just described is prevented.

At the bend where the elements 24 and 25 merge, a side plate 26 having inclined edge 21 is provided. This plate forms, with elements 24, 25 and 3|, a cradle for reception of the guard |2 and prevents it from slipping sidewise to the right or left as shown in Figures 1 and 3. It is thus that the nozzle is prevented from being dislodged from the nozzle support by accidental movements of either the nozzle or the hose 3 which is attached thereto.

The support I9 is also provided with a depending, inwardly curved portion 28 which is disposed below the axis of shaft l5 and affords a hand grip by means of which the shaft i3 may be actuated in either direction. If desired, the nozzle tip 4 or another part of the nozzle 1 may be engaged with the projection 28 for the p pose of pulling the shaft l6 outwardly. It should be noted that the portion 25 of the hose hook has substantial width, as shown in Figures 1 and 3, and that it is provided with a downwardly and outwardly slanting edge '29 which serves to prevent the nozzle guard 2 from being engaged with the hook 2| when the support H) is in any position except that shown in Figures 2 and 4; in other words, the lateral motion of the nozzle guard necessary to engage it with the hook 2| is prevented by element 25 in the Figure 5 or any similar position.

A boss 30, shown in Figures 1 and 3, is provided on the boss l5 and extends laterally therefrom. A guard plate or shield, preferably of stamped metal and indicated by the numeral 3|, is fixed to the boss 30 and also to the projection 24'by means of suitablefastenings such as drive screws, As shown clearly in'Figures 2 and 4, this plate 3| prevents access to the nozzle trigger II] from one side. also shroud the boss I 5 and the nozzle support l9, except for projection 28 thereof, when the latter is in the nozzle supporting position.

Formed in the back plate l3 are pockets 32 which support hinge pins 33. A second plate 34 is provided with hinges35 which are adapted to enter the pockets 32 and to receive the hinge pins 33. The plate 34 may thus be swung back substantially in contact with the outer surface of the back plate l3 so as to expose the nozzle support and the hook 2| from the right-hand side thereof, as shown in Figure 3, or it may be swung to a position in which it is parallel with the plate 3| so as to shroud and prevent access to the nozzle support, the trigger |B.and hook 2|.

The plate 34 is provided with a vertically extending perforation 36 which is adapted to receive the element 22, as shown clearly in Figure 3, so that the lock which enters the opening 23 in element 22 will lie outside of the plate 34 to hold it in its shrouding position.

An angle member has one leg 31 fixed in any desired manner to the plate 34 and has its other leg 38 extending in a direction substantially perpendicular to the plate 34. The leg 38 is of The plate 3| is of sufficient extent to such a length that when plate 34 occupie its shrouding position parallel to plate 3 the leg will engage a nozzle guard |2 immediately above the lower right-hand corner thereof, as shown in Figure 4, so that the nozzle cannot be lifted vertically from the support for the purpose of moving the trigger l0 out from the protection of the plates 3| and 34.

The back plate I3 is provided with a projection 39 in which is supported a shaft 44. A bell crank having a vertical arm 4| and a horizontal arm 42 is mounted to pivot on said shaft 46. The arm 4| is received in a slot 43 in the inner end of shaft l5 between two pins 44 so that the axial motion of shaft It will result in an up and down motion of the arm 42 of the bell crank. This movement of the arm 42 is transmitted through a link 45 to a lever 46 which is pivoted to the frame at 41 and to a second link 48 which is connected to both the lever 46 and link 45 at 49.

A register indicated generally by the numeral 50 is provided with a reset shaft 5| which is actuated in a known manner and serves to, in turn, actuate a shaft 52 of an interlock mechanism 53 shown in Figures 1 and 2. The internal structure of the interlock mechanism 53 is clearly disclosed in the application of C. P. Griffith, Serial No. 274,163, filed May 17, 1939. The seeker 54 and the cam element 55 of the interlock mechanism are pivoted at 56 on the lever 46. Both the lever and the interlock mechanism are supported on a cross member 51 which forms a part of the frame.

The link 48 is connected to actuate the lever 49 which, in turn, operates a switch 5!} which controls the motor 5|.

It will be seen that the nozzle support and the hose outlet are disposed as nearly as possible to the top of the dispensing apparatus housing so that a maximum length of hose ma be used in this apparatus.

Operation In operating this device, assuming that it has been locked up for the night, the operator must first unlock the padlock, not shown, and remove it from the perforation 23. He will next swing the plate 34, which has been released by removal of the look, from the full position to the dotted line position of Figure 3. In so doing the projection 38 which overlies the nozzle guard l2, as shown in Figures 4 and 6, will be withdrawn,

To remove the nozzle from the support the operator must lift nozzle 1 to a height sufficient to clear the edge 21 of plate 26, whereupon the nozzle can be moved laterally to the right pivoting about the nozzle tip 4 which is fulcrumed in boot 3, as viewed in Figure 3, to disengage the hook 2| from behind the nozzle guard I2. The nozzle is thus freed from the support and the hook 2| and the nozzle tip may then be withdrawn from the boot.

The operator may hook some portion of the nozzle or some portion of his hand under the projection 28 of the nozzle support and by pulling outwardly thereon actuate the bell crank 4|, 42 and the links 45, 48 to operate switch 50 to energize the motor 5! This operation will be blocked by the interlock mechanism unless the register 50 has been reset.

The next step will be to manipulate the valve trigger ID to dispense gasoline.

In order to restore the nozzle to the nozzle support it is first necessary, either by hand or by use of some part of the nozzle, to push the nozzle support If! and the shaft l6 inwardly or to the right, as shown in Figures 2, 4 and 5. If it is attempted to rest the nozzle guard 12 on the support IS without first pushing said support inwardly;-the parts being in the position shown in Figure 5, the nozzle guard 12 will be prevented from engaging the hook 2! by reason of the fact that the lateral motion of the nozzle necessary to eifect this engagement will be prevented by the edge '29 of the portion 25 of the nozzle support. It is not until this section 25has'been moved back into close juxtaposition with the back plate l3 that the guard may enter behind the hook 2|.

Anyattempt to support the nozzle on the portion 24 of the nozzle support without having first moved said support inwardly to the Figure 4 position will be defeated by the slipping of the nozzle guard down the inclined portion 24 of the support so that the nozzl will be dislodged. To look up the nozzle the first step of swinging plate 34 will be carried out in the opposite direction and thepadlock may then be replaced to hold the parts in the position shown in Figure 4.

When the nozzle is in its locked up position it is obvious that the elements 3| and 34 prevent any manual operation of the nozzle trigger it! by blocking access thereto. At the same time, the element 38 which is fixed to 34 prevents the nozzle from being lifted upwardly so as to bring the trigger upward and out from the protection of the shields to a position where the nozzle could be actuated manually.

Thus it will be seen that th nozzle is effectively locked in position by the mechanism disclosed herein and the nozzle trigger is shielded so that it cannot be manually operated'except when the mechanism is in the service or unlocked condition.

It is obvious that various. alterations may be madein the size, form, arrangement and construction of parts without departing from the spirit of the invention and for this reason applicant does not desire to belimited solel to the specific embodiment disclosedherein for purposes of explanation but rather he desires protection coveringsuch devices as may fall fairly within the scope of the appended claims.
